probably this,
- It would be physically impossible for me to read, comment, and upvote posts from every one of my followers. There are just not enough hours in the day to do this.
I get that its impossible, but having more followers isnt essentially a bad thing, Ive always asked people who have thousands of followers, but follow a few why they do that. No one ever gives a concrete answer, so i chuck it up to the psychological reason: more followers than following means the person is important, the more followers against following one has, the more people want to follow them because they seem important.(this is of cause, my own interpretation of a deeper social effect)
I have seen people like that too but that is another topic entirely. What I'm talking about is asking people to follow you for a follow back. It has no value whatsoever and is a waste of everyone's time.
This post is a prime example of how follow for follow does not work
